《哈他瑜珈之光》(于伽英文譯本)1.10:   

Like a house protecting one from the heat of the sun, Hatha Yoga protects its practiser from the burning heat of the three Tâpas; and, similarly, it is the supporting tortoise, as it were, for those who are constantly devoted to the practice of Yoga.就像房屋保護人免於太陽的灼熱，哈他瑜珈保護修行者免受各種苦；同樣，對於不斷地投身於瑜珈的修行者來說，它是支撐大地的神龜。
